Optical-storage-firewood switching system and grid-connected box

Abstract

The invention discloses an optical-storage-firewood switching system and a grid-connected box, the optical-storage-firewood switching system comprises a grid-connected box body, an upper shell, a lower shell and a plurality of photovoltaic panels, the photovoltaic panels are arranged outside the upper shell in a rectangular structure, outer frames are installed outside the photovoltaic panels, the outer frames are fixedly connected with the upper shell through hinge pieces, rectangular openings are formed in the side surfaces of the upper shell, and the rectangular openings are connected with the lower shell through hinge pieces. Limiting seats for limiting the photovoltaic panels are arranged in the rectangular openings, a plurality of positioning plates abutting against the inner side faces of the limiting seats are distributed in the upper shell in a rectangular structure mode, and supporting sealing pieces are perpendicularly installed at the corners of the upper shell and the corners of the lower shell. The photovoltaic grid-connected box is simple in structure, the photovoltaic panel has multiple use functions and is used in combination with the switching system, the photovoltaic panel can be automatically closed in rainy days while playing a role in power supply and sun shading, the grid-connected box body can be covered and sealed in combination with the upper shell and the lower shell, external rainwater is prevented from making contact with the grid-connected box body, and the service life of the grid-connected box is prolonged. And the heat of the grid-connected box can dry the water vapor entering the grid-connected box before.
